My invention relates to'an improved copwind er, the object being to produce a selfcontained individual Cop-Winder adapted in size and form to be applied directly to a loom so that the weaver may supply himself with the cops required for his work.

With these ends in view, my invention consists in a self-contained individual copwinder having certain details of construction as will be hereinafter described and pointed out in the. claims. a I Incarryingout my invention as herein shown, I employ a cop-winding spindle comprising a body-portion 2 and a tapering polygonal point 3. This spindle is ournaled at its rear end: in. a bearing 4 at the upper end of an upright 5 at the rear end of the machine-frame 6. The forward end of the spindle is journaled in a bushing 7 located within the cylindrical stem 8 of the winding-cone 9 which is formed as usual with a thread-slot 10,the said stem belng secured by a-set-screw 11 within a hub 12 located near the lower end of the main uprlght 13 of the machine-frame. The, spindle is driven bya' driving pulley 1. L secured to it by: a, set screw-15 and formed at itsforward end with a grooved extension 16. receiving a roundbel-t 17 runningover agroovedthreadguide pulley 18rturning on a. stud 19 fixed in a head 20 at the upper end. of the main upright 13 of the frame 6. The. said pulley l8 is provided with a. crank-pin 21 pro jecting from one side of the center of-a stud 2:2 adjustably mounted in the pulley and secured in any position'of adjustment therein by a set screw 23. The crank-pin 2-1 carries a crank-head 24: secured in.- place upon it by a cotter-pin 25 and receiving the bent upperend 26 of a crank-rod 27 the lower'end 28 of which is bent at a right angle" and passed transversely through the head of a rocking-stud 29v j'ournaled in: a

boss 30 formedat, the outer end of a threadguide: lever 31, rockingupon a stud 32 in the main-frame 6. The said lever 31'i's formed with a segmental slot 33 receiving a binding-screw 34* which passes: through the said slot and into a thread-guide arm'35 the lower end of which alsofroeksupon the stud 32.. The upper end of the said: arm 35 can ries a thread-guide 3 6 secured in place by a screw 37, and extending upward and over the thread-slot 10in, the winding-cone 9:. By means of the segmental slotf33-and the screw 34, the arm 35-may be adjustedwith respect to' the rocking-lever 31, and hence changed in the position of its throw.

The, driving-belt 38 running over the pulley 14, is automatically shifted to a loose pulley 39, also mounted upon the; Spindle 2, by means of two belt-shifting arms 40 suitably spaced apart and rising from a wide collar 41 secured to a longitudinally movable belt-shifter rod 42: bearingat its rear end in the upright 5 and at its inner end inthe lower end of the main upright 13, the forward end of the rod havingan upstanding operating manual or handle 43. The said rod is prevented from rocking by means of an arni l t secured to it by aset screw 45 and having its lower end perforated for the reception of a rocking trip ping-rod 46 over which it rides back and forth. t

For. the purpose of automatically stopping the machine upon the completion of the winding-of a cop, I employ a beveled cut-off or tripping-lever 47 secured to the rocking tripping-rod 46 upon which it is adjusted according to the length. of the cops to be wound, the said rod 46 having hearing at its rear end in the upright 5 of the frame and at its forward end in a bracket 48 secured to a fixed rectangular slide-bar 49, the rod-like rear end 50 of which passes through a bore 51 in the lower end of the main upright 13, and a bore 52 in the upright 5. The bar 49 is located below the spindle and the winding cone and in the vertical plane thereof. At its rear end the rod 46 is provided with a latch-finger 53 secured to it by a set screw 54 and adapted at its upper end to entera notch 55 in the inner face of the belt-shifter rod 42. A helical spring 56 connecting the said screws 45 and 54, exerts a constant effort to draw the rod 42 rearward so as to cause the belt-shifter to transfer the belt 38 from the driving pulley 14 to the loose pulley 39. A helical spring 57 secured at its upper end to an eye 58 in the upright 5 and at its lower end to an arm 59 applied to the projecting rear end of the rod 42, exerts a constant effort to rock the said rod and cause the latch-lever 53 to enter the notch 55 in the belt-shifter rod 42. The slide-bar 49 aforesaid, carries a slide 60 having an upright 61 supporting a horizontal tubular bearing 62 mounting a rotatable trunnion 63 centering and supporting the cop-butt 64, the trunnion 63 having a circumferential groove 65 receiving a retaining-screw 66. A finger-piece 67 depending from the bearing 62, provides for manually moving the slide away from the winding-cone 9 and against the power of a weight, not shown, but carried by a cord 68 secured to the slide by an eye 69 and running over a pulley 70 on a stud 71 in the frame 6.

A thread-hook 72 located substantially above the thread-guide 36 is mounted in the upper end of the main upright 13 in which it is secured by a set screw 73.

In using my improved machine, the slide 60 is moved by its finger-piece 67, away from the winding-cone 9 against the power of the weight attached tothe cord 66, so as to clear the winding-cone and permit a copbutt to be forced over the tapered end 3 of the winding-spindle, one end of the yarn to be wound into a cop having previously been attached to the cop-butt. The manual 43 is now grasped and the rod 42 slid forward to the limit of its throw in that direction, whereby the belt 38 is shifted from the loose pulley 39 to the driving pulley 14, thus starting the spindle rotating and the thread-guide lever and arm rocking. As the belt-shifter rod 42 reaches the limit of its forward movement the spring 57 forces the latch-lever 53 into the notch 55 of the rod, whereby the belt-shifter is locked in its driving position. Now as the cop-tube is built up in the usual manner, the pressure of its inner or building end against the interior walls of the winding-cone, gradually moves the slide 60 outward against the power of the weight depending from the cord 68. This continues until the said slide engages with the tripping or cut-off lever 47 and depresses the same sufficiently to rock the rod 46 against the tension of the spring 47 and so disengage the latch-lever 53 from the notch 55 in the belt-shifter rod 42. The spring 56 now asserts itself to pull the rod 42 rearward so as to shift the belt 38 from the driving pulley 13 to the loose pulley 39, whereby the machine is stopped.

The diameter of the cop-tube thus produced is determined by the throw of the thread-guide arm 35 which is regulated by shifting the position of the crank-pin 21 by turning the stud 22 in the thread-guide pulley 18. The position of the throw of the thread with respect to the winding-cone 9 is regulated by the segmental slot 33 and binding-screw 34 which permits the threadguide arm 35 to be shifted in position with respect to the rocking thread-guide lever 31.

By my improved construction and ar rangement of parts, I am enabled to produce a thread-guide so compact in form and requiring so little space for its operation, that it may be applied to an ordinary loom withoutinterfering with the full and free use of the same, whereby a weaver is enabled to wind his own cops. In my improved device, I dispense with the use of the train of gears generally employed for driving the thread-guide. It will also be noted that the train of parts operating the thread-guide mechanism is located substantially above the cop-winding spindle and winding-cone rather than to the side thereof as heretofore. 105 It will be further noted, that by employing a slide on a slide-bar, the space requiredfor the operation of the machine is much reduced over that required for the operation of machines employing a longitudinally 110 movable slide-bar carrying at one end a fiX- ture provided with the trunnion used for centering and supporting the cop-butt.

I claim 1. In a self-contained, portable individual 115 cop-winding machine, the combination with a horizontal frame having upstanding bearings and an upright and adapted to be mounted in a horizontal position upon a loom-frame, of a cop-winding spindle lo- 120 cated above the said frame and journaled in the said upstanding bearings, a windingcone'concentric with the said spindle, a movable thread-guide, a driving pulley concentrio with the said spindle, and driving means 1 mounted upon the said upright for operating the said thread-guide.
